pmma is dangerous - France, FR
Never USE I repeat NEVER USE hydrogel...
I had it in my lips and I had to do remove it by a surgeon because about 5 years I got complications like bumps/lumps and the product spread down above my lips, in my cheek and my jaw. it was awful!!
Even if a surgeon inject you, you will have later big problems!!! because youy body will react because of the product is a foreign product.
Do reseach on web it's very dangerous!!
